glCreateShaderProgramv: create a stand-alone program from an array of null-terminated source code strings
Function Definition
GLuint glCreateShaderProgramv(GLenum type, GLsizei count, const char **strings);
- type
- Specifies the type of shader to create.
- count
- Specifies the number of source code strings in the array strings.
- strings
- Specifies the address of an array of pointers to source code strings from which to create the program object.
Description
glCreateShaderProgram creates a program object containing compiled and linked shaders for a single stage specified by type. strings refers to an array of count strings from which to create the shader executables.
glCreateShaderProgram is equivalent (assuming no errors are generated) to:
const GLuint shader = glCreateShader(type);
if (shader) {
glShaderSource(shader, count, strings, NULL);
glCompileShader(shader);
const GLuint program = glCreateProgram();
if (program) {
GLint compiled = GL_FALSE;
glGetShaderiv(shader, GL_COMPILE_STATUS, &compiled);
glProgramParameteri(program, GL_PROGRAM_SEPARABLE, GL_TRUE);
if (compiled) {
glAttachShader(program, shader);
glLinkProgram(program);
glDetachShader(program, shader);
}
/* append-shader-info-log-to-program-info-log */
}
glDeleteShader(shader);
return program;
} else {
return 0;
}
The program object created by glCreateShaderProgram has its GL_PROGRAM_SEPARABLE status set to GL_TRUE.
Errors
GL_INVALID_OPERATION is generated if pipeline is not a name previously returned from a call to glGenProgramPipelines or if such a name has been deleted by a call to glDeleteProgramPipelines.
GL_INVALID_OPERATION is generated if program refers to a program object that has not been successfully linked.
